Definitions
- the present invention relates to a plug-in connector capable of simply and appropriately connecting an electric wire with another electric wire only by inserting one end portion of the electric wire.
- a contact element comprising a conductive plate for connecting electric wires with each other and a spring piece for urging an electric wire against the conductive plate is incorporated in a holder made of a heat-resistant insulating member.
- Wire connection can be easily performed by anybody only by peeling the coatings on the connection ends of electric wires to be connected and inserting the peeled portions through the insertion ports of the holder.
- plug-in connectors having various types of structures are conventionally known, e.g., one disclosed in Japanese Utility Model Publication Nos. 1-22228, 1-29738, and the like.
- this plug-in connector is a simple and assembly-facilitated pressure contact structure by means of the contact element of an electric wire.
- peeled portions of the electric wires as electric wire connection ends can be easily inserted in the holder, and after insertion, the peeled electric wire portions are reliably prevented from removal from the holder, so that the contact element and the electric wire peeled ends by pressure connection in this state can electrically contact each other with a high reliability.
- a conventional contact element comprising a conductive plate made of a copper member or the like and a leaf spring having a spring piece for urging the peeled electric wire portions against the conductive plate is used.
- the conventional contact elements however, one which not only has a simple structure and can be assembled easily, but also can satisfy easy insertion of the peeled electric wire portions to be inserted, reliable electrical connection by ensuring a contact area and a contact pressure, and prevention of the inserted peeled electric wire portions from removal has not yet been proposed.
- a plurality of electric wire insertion holes are formed in one plate portion of an L-shaped bent conductive plate, a caulking piece is provided on the outer end of the conductive plate, and projecting portions provided to part of the caulking piece are caulked through holes formed in the leaf spring, thereby fixing the proximal end portion of the leaf spring on the conductive plate.
- the portions of the conductive plate having the electric wire insertion holes and the caulking portion are deformed in a direction to move the distal end portion of the leaf spring away from the electric wires to decrease the pressure. As a result, the electrical conductivity is degraded.
- the distal end side of the leaf spring can easily float from the conductive plate depending on the caulked state of the fixing portion fixed by caulking. Then, a gap between the leaf spring and the electric wire receiving portions of the conductive plate becomes larger than the diameter of the electric wires. Even when the electric wires are inserted, the leaf spring cannot firmly catch the electric wires. Removal of the electric wires may not be prevented.
- An angle defined by the distal end side of the leaf spring, fixed by caulking to the conductive plate, and the conductive plate is significant in facilitating the plug-in operation of the electric wires and reliably preventing the electric wires from removal. More specifically, considering facilitation of wire insertion and reliable electrical connection of the electric wires, when the angle defined by the conductive plate and the leaf spring, both constituting the contact element, is set small, the function of the leaf spring that prevents the electric wires from removal is impaired. On the other hand, when the angle is set large in order to cause the leaf spring to firmly catch the electric wires and to reliably prevent the electric wires from removal, the electric wires cannot be easily inserted between the conductive plate and the leaf spring both constituting the electric wire contact element. In addition, a contact area cannot be ensured, thereby impairing electrical connection.
- a substantially U-shaped bent conductive plate and an almost V-shaped leaf spring incorporated inside the conductive plate are used.
- One plate portion of this leaf spring is arranged along the inner surface of one side portion of the conductive plate.
- the other plate portion of the leaf spring obliquely extends toward the other end portion thereof.
- the conductive plate and the leaf spring have a simple structure and can be assembled easily, there is a problem in obtaining the required clamped state of the electric wire peel portions. More specifically, when the peeled electric wire portions are inserted to flex the leaf spring at an acute angle, the reactive force of the leaf spring also acts on one bent side portion of the conductive plate to open the U-shaped conductive plate. Then, the clamped state of the peeled electric wire portions by means of the leaf spring cannot be maintained, and the reliability of the electrical connection of the electric wires cannot be ensured. In addition, the electric wires cannot be prevented from removal. Therefore, it is required to take a countermeasure that can solve all these problems.
- Another one of the requirements of the plug-in connector described above is to recognize and discriminate whether the connecting ends of electric wires are reliably connected to each other by inserting them in the holder.
- an electric wire insertion identification piece that can be swung upon inserting an electric wire is provided to part of the holder of the connector. The motion of the identification piece is grasped visually or by the sense of touch.
- an object of the present invention to provide a plug-in connector which can constitute a contact element allowing electrical connection of peeled electric wire portions by combining a leaf-like spring member and a conductive plate which are easily formed by simple bending, while having good workability and easy assembly, and which can reliably clamp the peeled electric wire portions under pressure, thereby ensuring reliability of electrical connection.
- a plug-in connector comprising a contact element constituted by a conductive plate having insertion holes in which peeled portions of a plurality of electric wires are inserted, and a leaf-like spring member integrally mounted on the conductive plate and having a plurality of tongue pieces for urging the inserted peeled electric wire portions against part of the conductive plate, and a holder for incorporating the contact element and made of a synthetic resin material having a heat-resistant insulating property, wherein the conductive plate is made of at least a first plate portion and a second plate portion bent with respect to the first plate portion, the first plate portion having the insertion holes formed therein, and the leaf-like sprig member has one end hooked and locked by a distal end side of the second plate portion of the conductive plate, the other end having the tongue pieces for urging the inserted peeled electric wire portions against the second plate portion of the conductive plate, and a folded portion formed at least at one portion between one
- Figs. 1 to 5 show a plug-in connector according to an embodiment of the present invention.
- this embodiment exemplifies a plug-in connector of a type for connecting three electric wires 1.
- Single-core electric wires are generally used as the electric wires 1.
- the insertion ends of the electric wires 1 serving as the connection ends to be connected to the connector are prepared as peeled portions 2 obtained by peeling insulating coatings 1a.
- a plug-in connector 10 comprises a holder 11 and a cap 12.
- the holder 11 is integrally made of a heat-resistant insulating synthetic resin material to have a substantially box-like shape.
- the cap 12 is made of a heat-resistant insulating synthetic resin material, as in the holder 11, to close the end open to the electric wire insertion end of the holder 11.
- Three electric wire insertion ports 13 into which the peeled electric wire portions 2 of the electric wires 1 are inserted as needed are formed in the cap 12.
- each electric wire insertion port 13 formed in the cap 12 has a larger diameter so that each electric wire insertion port 13 has a substantially horn-like shape. Hence, the electric wires 1 can be easily inserted into the electric wire insertion ports 13.
- one engaging projection 15a is formed on one side of the cap 12, and two engaging projections 15a are formed on the other side of the cap 12 in a staggered manner. This aims at preventing the cap 12 from being mounted upside down when the cap 12 is to be mounted on the holder 11 after a contact element 20 (to be described later) is incorporated in the holder 11, thereby obtaining good workability and high reliability.
- the contact element 20 is disposed in an internal space 14 formed in the holder 11 closed by the cap 12, and clamps the peeled electric wire portions 2 under pressure, thereby electrically connecting the electric wires 1 to each other (not shown).
- the contact element 20 is constituted by a conductive plate 21 and a leaf-like spring member 22.
- the conductive plate 21 is formed of a substantially U-shaped bent conductive plate member, e.g., a copper plate plated with tin or the like.
- the leaf-like spring member 22 is integrally mounted on and held by the conductive plate 21 and clamps the peeled electric wire portions 2 together with the conductive plate 21 under pressure, thereby electrically connecting the electric wires 1 to each other.
- the conductive plate 21 and the leaf-like spring member 22 are formed to have a shape as shown in Figs. 1 to 3 and assembled integrally, thereby forming the contact element 20.
- the substantially U-shaped conductive plate 21 comprises a proximal end portion 26 and long and short bent pieces 27 and 28.
- a plurality (three) of electric wire insertion holes 25 corresponding to the electric wire insertion ports 13 are formed in the proximal end portion 26 so that the peeled electric wire portions 2 can be inserted therein.
- the long and short bent pieces 27 and 28 are formed by bending the two edges of the proximal end portion 26 in an electric wire insertion direction.
- Reference numerals 29 denote a plurality of projecting portions.
- the projecting portions 29 are formed on the long bent piece 27 such that the central portions of the electric wire insertion holes 25 constitute V-shaped guide grooves 29a, as shown in Fig. 5.
- the projecting portions 29 increase the contact portion between the conductive plate 21 and the peeled electric wire portions 2, so that electrical connection can be reliably achieved.
- the leaf-like spring member 22 has a catch piece 30 on its one end side to be caught by the distal end of the long bent piece 27 of the conductive plate 21.
- the other end side of the leaf-like spring member 22 forms strips to constitute a plurality of tongue pieces 31 serving as electric wire pressure contact pieces.
- This other end side of the leaf-like spring member 22 extends obliquely downward in a tilted manner as its folded portion 32 is engaged with the inner side of the corner portion of the short bent piece 28 of the conductive plate 21.
- the overall leaf-like spring member 22 substantially has a trapezoidal shape, wherein part thereof having the catch piece 30 on its one side stands upright in a direction perpendicular to the electric wire insertion direction and then is bent in the electric wire insertion direction to reach the folded portion 32.
- reference numeral 33 denotes a wall portion extending perpendicularly to the electric wire insertion direction.
- Second electric wire insertion holes 34 are formed in the wall portion 33 to oppose the electric wire insertion holes 25 of the proximal end portion 26 of the conductive plate 21.
- the peeled electric wire portions 2 extend through the contact element 20 consisting of the conductive plate 21 and the leaf-like spring member 22. At this time, the peeled electric wire portions 2 can have an appropriate electrical contact state within the contact element 20.
- Reference numeral 35 denotes a resilient piece portion extending from the wall portion 33 toward the folded portion 32 in the electric wire insertion direction.
- the conductive plate 21 and the leaf-like spring member 22 having the above arrangements are assembled as they are integrally combined when the catch piece 30 of the leaf-like spring member 22 is caught by the distal end of the long bent piece 27 of the conductive plate 21, the folded portion 32 of the leaf-like spring member 22 is engaged with and held by the short bent piece 28 of the conductive plate 21, and the plurality of tongue pieces 31 are urged against the long bent piece 27 with a predetermined resilient force. More specifically, this contact element 20 has a stable combination of two members that can be obtained by simple bending.
- Step portions 40 are formed on the inner wall portion of the holder 11 to define the incorporating position of the contact element 20 in the deep portion of the holder 11.
- the left side in Fig. 1 of the contact element 20 incorporated in the holder 11 is locked by the inner end of the cap 12 which is fitted in and locked by the open end of the holder 11.
- the contact element 20 is prohibited from moving in the holder 11, so that it is incorporated in the holder 11 without a backlash.
- the electric wire insertion holes 25 and 34 for inserting the peeled electric wire portions 2 therethrough are formed in the conductive plate 21 and the leaf-like spring member 22, respectively. Since the peeled electric wire portions 2 are inserted such that they extend through the contact element 20, the leaf-like spring member 22 having the tongue pieces 31 and the like are not excessively urged in the holder 11. Therefore, the respective portions will not be deformed excessively, which is advantageous in terms of the service life.
- the strip-like tongue pieces 31 of the leaf-like spring member 22 firmly catch the peeled electric wire portions 2, that are being inserted along the inner side surface of the long bent piece 27 of the conductive plate 21, such that they apply a resilient force to the peeled electric wire portions 2, and urge the peeled electric wire portions 2 against the long bent piece 27, thereby assuring the electrical contact state and to prevent the peeled electric wire portions 2 from removal.
- a recessed checking groove portion 41 is formed in the front surface portion of the insertion side of the cap 12 in order to serve as the standard to measure the length of the peeled portions 2 of the electric wires 1 that are inserted in the plug-in connector 10.
- the length of the coatings to be removed from the insertion end portions of the electric wires 1 that are to be connected by the plug-in connector 10 of this type can be determined to a substantially constant value.
- the peeling amount of the insulating coatings 1a may be adjusted in accordance with this substantially constant value, and thereafter the electric wires 1 may be inserted into the plug-in connector 10.
- the recessed checking groove portion 41 is generally formed in the side surface portion or the like of the holder 11.
- the connector 10 when the electric wires 1 are to be inserted, the connector 10 must be passed from one hand to the other hand to adjust the length of the coatings to be removed front the insertion end portions of the electric wires 1, inevitably resulting in a cumbersome operation.
- the peeling length of the peeled portions 2 of the electric wires 1 can be adjusted or the peeled electric wire portions 2 can be inserted while the electric wires 1 oppose the insertion surface of the holder 11, thus providing a large practical advantage.
- the proximal end portion 26 of the conductive plate 21 and the wall portion 33 of the leaf-like spring member 22 are arranged to block the electric wire insertion direction.
- the first and second electric wire insertion holes 25 and 34 are formed in the proximal end portion 26 and the wall portion 33, respectively, so that the peeled electric wire portions 2 clamped with pressure between the conductive plate 21 and the leaf-like spring member 22, that constitute the contact element 20 incorporated in the holder 11, extend through the holes 25 and 34.
- the peeled electric wire portions 2 are thus held by the electric wire insertion holes 25 and 34 to extend through the conductive plate 21 and the leaf-like spring member 22.
- the holder 11 is made of a transparent synthetic resin material so that the interior of the holder 11 can be visually confirmed.
- the coatings on the insertion ends of the electric wires 1 to be connected are peeled.
- the peeled electric wire portions 2 are inserted into the insertion ports 13 of the cap 12 and urged under pressure by the strip-like tongue pieces 31 of the leaf-like spring member 22 against the conductive plate 21 of the contact element 20 incorporated in the holder 11, so that the electric wires 1 can be electrically connected to each other.
- the distal ends of the peeled portions 2 of the electric wires 1 can be visually confirmed through the transparent holder 11, as is apparent from Figs. 1 and 2. Therefore, the inserted state of the electric wires 1 can be easily and reliably confirmed from the outside of the holder 11.
- the present invention is not limited to the structure of the above embodiment.
- the shape and structure of the respective portions e.g., the conductive plate 21 and the leaf-like spring member 22 constituting the contact element 20, may be appropriately modified and changed.
- Various modifications may be made regarding the shape and structure of the holder 11, the cap 12, and the like constituting the plug-in connector 10.

- a plurality of strip-like tongue pieces to be engaged with an inner side of the short bent piece extend obliquely from the other end side of the leaf-like spring member toward the long bent piece. Since second electric wire insertion holes are formed in part of the leaf-like spring member to oppose the electric wire insertion holes in the proximal end portion of the conductive plate, excellent effects can be obtained as follows despite the simple arrangement.
- the conductive plate and the leaf-like spring member both constituting the contact element are simplified, so that the contact element facilitating electric connection of electric wires to each other can be obtained with simple bending and combining operations.
- the tongue pieces of the leaf-like spring member firmly catch the peeled electric wire portions at a required pressure, thereby urging the peeled electric wire portions, so that the electric wires can be electrically connected by the contact element in a required state. Therefore, requirements for reliable electrical connection and prevention of removal of the electric wires by means of appropriate catching can be satisfied.
- a contact element for connecting electric wires with each other is constituted by a leaf-like spring member and a conductive plate.
- the leaf-like spring member has a hook-like catch portion formed by bending at one end thereof and a plurality of tongue pieces that are formed at the other end thereof to have a strip shape.
- the tongue pieces are bent toward the hook-like catch portion through a folded portion.
- the conductive plate is formed by bending to have a substantially L shape.
- One end portion of the conductive plate hooks and locks the hook-like catch portion.
- the other end portion of the conductive plate forms a portion bent inwardly.
- the bent portion embraces and holds the folded portion of the leaf-like spring member. Therefore, despite the simple and inexpensive arrangement, the contact element for clamping the inserted electric wires under pressure can be constituted very simply such that it can reliably connect the electric wires under pressure.
- This contact element is excellent in terms of workability, assembly, and cost performance.
- one end portion of the leaf-like spring member is formed to have strips. Every other strip forms a hook-like catch portion, and the remaining strips form second tongue pieces to urge against the peeled electric wire portions. Therefore, in addition to the advantages described above, electrical connection between the peeled electric wire portions to each other and a function of preventing the electric wires from removal by means of catching can be enhanced more reliably.
- the holder for incorporating the contact element described above is made of a transparent heat-resistant insulating synthetic resin material so that the distal ends of the peeled electric wire portions extending through the contact element from the electric wire insertion holes can be visually confirmed from the outside of the holder. Therefore, despite the simple and inexpensive arrangement, in inserting the peeled electric wire portions, when the inserted electric wires extend through the contact element while they are urged by the contact element, the distal ends of the peeled electric wire portions are visually confirmed through the transparent holder, so that confirmation of the electric wire insertion operation can be simply and reliably performed from the outside of the holder.
